T0 @ZZ whom, it may concern:

Y Beit known that I, JAMES H. REED, of Lynn, in the county of Essex,State of Massachsetts, have invented certain new and useful Improvementsin Machines for Cutting and Beveling Boot or Shoe Soles, of which thefollowing is a description sufficiently full,clear, and exact to enableany person skilledin the art or science to which said inventionappertains to make and use the same, reference being had to theaccompanying drawings, forming part of this specification, in which-Figure 1 is a front elevation of my improved machine, the standard beingrepresented as broken off; Figs. 2 and 3, vertical longitudinal sectionsshowing diiferent forms of beveling cutter-heads; Fig. 4, an elevationof the rotary cutter-head viewed from the left in Fig. 1, the shaftbeing shown in cross-section taken on line x Fig. 5, a like view of thesliding cutter-head, taken on line y y in Fig. l; Fig. 6, an elevationof the gage-ring shown in Fig. 2 detached; Fig. 7, a like view of thering shown in Fig. 3; Fig. S, a plan View showing section of leatherwith pattern attached; Fig. 9, a plan view of a portion of the sole,showing edges beveled; Fig. 10, an inside plan of the sole, showing thewelt; Fig. 11, a vertical section taken on line o fn in Fig. 8; Fig. 12,a like view on line w w in Fig. 10; and Fig. 13, a like View taken online z a in Fig. 9.

Like letters and numerals of reference indicate corresponding parts inthe different figures of the drawings.

My invention relates to a machine for shaping and chamfering boot andshoesoles; and it consists in certain novel features hereinafter fullyset forth and claimed, the object being to produce a simpler, cheaper,and more effective device of this character than is now in ordinary use.

The nature and operation of the improvement will be readily understoodby all con- Versant with such matters from the following explanation:

In the drawings, A represents the standard or body of the machine, whichis provided with a forked head b. A horizontal rotary shaft d isjournaled in the arms of said head and is provided with a fly-wheel fand drivepulley g. The shaft is splined at h and has its I endsscrew-threaded at i. A circular cutterheady' is detachably secu red onthe threaded end of the shaft bya set-screw k. A gagecap m, providedinteriorly with a threaded socket p, is turned onto the end of saidshaft and incloses the head j. A series ot' curved blades r are securedto the face of the head j opposite the cap m by clamping-bolts t,passing through said head. Said blades are eccentrically arranged, (seeFig. 4,) and are adjustable longitudinally, their cutting-edges beingWithin the peripheral line of said head, which is notched laterally atl5. A head 16 is litt-ed to slide on the spline, and has an annulargroove in which a collar 17 is disposed. Rods 18, fitted to slidelongitudinally in lugs 19 on the fork b, are secured to said collar. Oneend of said rods is threaded and a checknut 20 thereon limits theirlongitudinal movement. A lever 2l is pivoted to a bracket 22 on thefork, one end being slotted at 23 to receive a pin on the rod. Saidlever is connected by a rod 24 with a treadle at the foot of thestandard, whereby the head 16 may be moved longitudinally on the shaft.A cylindrical stock B is adapted to inclose the head 16, and is providedat one end with an annular fiange 25, arranged atri ght angles to thebody of the stock and at the opposite end with longitudinal slots 26.Set-screws 27 pass through said slots into the head, securing the stockthereon. The stock has an interior flange 30, grooved at 2 3 and 29 (seeFig. 6) to respectively receive the blades r and bolts t on the head jwhen said heads are forced into engagement. A series of blades 35 arelongitudinally adj ustable on the head 16 byset-screws 36,the stock Bbeing` slotted to receive said screws and ad-Y mit adjustment of theknives. The cuttingedges 4.0 of the blades may be arranged vertically at:right angles, as in Fig. 1, or inclined inwardly, as in Figs. 2 and 3.The flange 25 of the stock has openings 41, through which said edgesproject, said openings occupying the position and performing likefunctions with the abutment of an ordinary plane.

In the use of myimprovement the cap m is adjusted on the head j at asuitable distance from the inner edge thereof, leaving a bearing-space50 to receive the edge of the pattern IOO C. The pattern, being securedto the stock D in the usual manner, is held vertically with its edgeresting on the head at 50. Thetreadle is then depressed, forcing thesliding head 16 outward, its blades engaging the rough or uniinishedface of the leather. Said heads being rotated, the blades fr trim theleather D, shaping the sole to conform to the outline of the pattern,which is turned by the operator against the head j. The knives 40 reducethe stock to even thickness while the sole is being formed.

In Fig. 2 the head j is replaced by a plain head 51 without knives r,and the stock B has a flange 71, beveled vertically. The knives 35 inthis form have cutting-edges which are inclined at the same pitch as thestock-flange, but are slightly shorter than the opening 41, leaving aspace 52. This form is employed to scarf the edges ot' an inner sole, asshown at 54 in Fig. 13, and leaves a slight shoulder 53 for stitchingsaid sole. The head 51 is provided With notches l5, into which the toeof the blades project when the sliding head is forced outward. The soleis held against the cap and head and the knives form the bevel. Bymoving the cap toward the blades the bevel may be adjusted to reduce theleather to a feather-edge, if desired.

In the form shown in Fig. 3 the beveled flange 7l is shorter and theknives 35 have a shorter cutting-edge. This is employed to chamfer theinner edges of an outer sole after the welt 60 (see Fig. 12) has beenturned up, forming the bevel 6l. The openings 4l in the stock-flanges 25permit the leather shaved from the sole to pass through after the mannerof the ordinary plane.

Any number of adjustable stocksB, provided With inclined flanges andinterchangeable on the sliding head, may be employed, the cutting-edgesof their knives being 1nclined to suit the character of the Work.

Havingthus explained my invention, what I claim isi- 1. The combinationof tho rotary shaft with the head j fixed thereon, the adjustablegagecap fm, adjustable on said shaft and overlap ping said head from itsouter face, and the eccentrically-arran ged curved knivesr, clamped onthe inner face of said head and adjustable longitudinally, substantiallyas described.

2. The rotary shaft and guide-head fast thereon, in combination with thesliding head 16 on said shaft, a treadle mechanism for moving said headlongitudinally, the stock B, adjustable on said sliding head andprovided at its inner end with the beveled Iiange having blade-openings41, and the adjustable knives 35 on said stock, provided withvertically-inclined cutting-edges projecting through said openings,substantially as described.

3. In a sole cutting and beveling machine, the rotary shaft, notchedguide-head fast thereon, and adjustable gage-cap overlapping said head,in combination with the shapingknives r on said head, the sliding head1G on said shaft, and actuating mechanism, the detachable knives 35,secured to said sliding head, and the adjustable flanged stock B on saidsliding head, having blade-openings 4l, 28,and 29, arrangedsubstantially as described.
